- The exam has 35-45 questions in 50 minutes, so pacing is tight but the content is foundational.
- The passing score is 700 on a 1-1000 scaled scale, not a flat 70% of questions correct.
- The official objectives cover four areas: Defense in Depth, Operating System Security, Network Device Security, and Secure Computing.
- The US retail voucher with retake costs USD 133, and the retake code must be used within 60 days.
The Honest Difficulty Verdict
The Information Technology Specialist - Network Security exam is an entry-level certification exam, and its difficulty should be judged on that footing. It does not demand deep packet analysis, advanced cryptography math, or incident response at scale. What it does demand is breadth: you need to recognize the right security control for a given situation across Windows and Linux systems, wireless networks, firewalls and monitoring tools, and everyday end-user computing habits.
For a candidate who has configured file permissions, set up a firewall rule, and read an audit log, the exam is manageable with focused review. For a candidate who has only read definitions, it can feel harder than expected, because the questions tend to ask you to choose a control rather than define one. If you want the complete roadmap, our ITS-NS study guide breaks the preparation into a first-attempt plan.
What You Are Actually Facing: Format and Scoring
Understanding the mechanics removes a lot of unnecessary anxiety. The exam is computer-based and proctored. Pearson publishes a range of 35-45 questions with a standard exam time of 50 minutes, excluding administrative appointment activities such as check-in and identity verification. The official tutorial illustrates multiple-choice questions along with review and navigation features that let you revisit and change answers before you submit.
| Exam Element | What the Official Sources Say |
|---|---|
| Question count | 35-45 questions (published range, not a fixed total) |
| Time | 50 minutes standard, excluding administrative activities |
| Delivery | Computer-based and proctored |
| Passing score | 700 on a 1-1000 scaled score |
| US retail voucher with retake | USD 133 (proctoring at some testing centers may cost extra) |
| Voucher validity | 1 year from purchase; retake code must be used within 60 days of a failure |
Two details here deserve emphasis. First, the 700 passing mark is a scaled score, so you should not assume it equals 70% of questions answered correctly. Our page on the ITS-NS passing score explains how to think about it. Second, the time pressure is real but moderate: at the high end of 45 questions in 50 minutes, you have a little over a minute per question, which is comfortable for items you know and tight if you stall on scenarios you have never practiced.
Where Candidates Struggle by Domain
Difficulty is not evenly distributed. The official objectives are organized under four headings, and each one stresses a different kind of thinking. The ordering below reflects editorial judgment about where preparation tends to pay off most, not official percentage weights. For a deeper walkthrough of each area, see the complete guide to the four ITS-NS content areas.
Domain 1: Defense in Depth
This domain is conceptual, which is exactly why it trips up candidates who rely on rote definitions. You need to understand why layered controls exist and be able to place a given control at the right layer.
- Recognizing how physical, network, host and user-level controls complement one another
- Distinguishing preventive, detective and corrective measures in a scenario
- Understanding network isolation and why segmenting traffic limits damage
- Choosing appropriate backup approaches as part of a resilience strategy
Domain 2: Operating System Security
For many candidates this is the most hands-on and the most rewarding area to practice, because the concepts map directly to things you can configure in a lab.
- Windows and Linux file and folder permissions, and how they combine
- Authentication methods and the principle of least privilege
- Auditing: what to log and how to read the results
- Encryption of data at rest, including when disk or file encryption is the better choice
Domain 3: Network Device Security
This is where terminology collisions cause the most wrong answers. Firewalls, IDS, IPS and SIEM sound similar and do different jobs.
- Firewall behavior and rule logic, including why rule order matters
- The difference between detecting traffic (IDS) and blocking it (IPS)
- What a SIEM does with logs from many sources
- Wireless protection and secure protocol selection
Domain 4: Secure Computing
This domain covers safer end-user computing. It looks easy and is often underestimated, but the questions are scenario-driven and reward careful reading.
- Recognizing common attack patterns aimed at ordinary users
- Safe browsing, updates and malware protection habits
- Applying secure practices to everyday workplace situations
If you only have time to deepen one area, make it Operating System Security, because permission and authentication scenarios appear in many forms and are easy to practice on a personal machine or virtual lab.
Why Pass-Rate Claims Don't Settle the Question
Candidates naturally search for a pass rate to gauge difficulty. Here is the uncomfortable truth: no candidate-wide pass rate is published for this exam, and any specific percentage you see online should be treated with suspicion. Numbers quoted by training vendors, schools and course sellers typically describe their own cohorts, which are self-selected and prepared in a particular way. They do not describe the exam population as a whole, and a vendor guarantee is a marketing promise, not a measurement.
A better difficulty gauge is your own performance on objective-mapped practice questions. If you can explain why each wrong answer is wrong, you are in good shape regardless of what any aggregate number says.
Who Finds It Easier and Who Finds It Harder
Pearson describes the target candidate as someone with hands-on familiarity with client operating systems, security applications, firewalls, devices and network ports, plus roughly 150 hours of instruction or practical experience in network security. That figure is preparation guidance, not an exam requirement and not a mandatory course. There is no bachelor's degree requirement, which you can confirm on our ITS-NS requirements page.
| Candidate Background | Likely Experience |
|---|---|
| Help desk or desktop support worker | Comfortable with permissions and updates; needs focused work on IDS/IPS/SIEM distinctions and defense-in-depth reasoning |
| Student in a networking or IT program | Strong on terminology; often needs lab time to turn definitions into decisions |
| Career changer with no IT exposure | Faces the steepest climb; should build hands-on familiarity before booking the exam |
| Linux-only or Windows-only user | Needs to close the gap on the other operating system's permission and auditing model |
The single biggest predictor of difficulty is whether you have worked in both a Windows and a Linux environment. The objectives cover both, so a one-platform background leaves a predictable hole.
Scenario Thinking: The Skill the Exam Rewards
Because questions ask you to choose a control for a situation, practice the decision, not just the definition. Work through exercises like these until the reasoning is automatic:
- Permissions: A user can read a file but cannot save changes. Which permission is missing, and how would you grant it without over-granting access to the whole group?
- Firewall vs. IDS vs. IPS: You need a tool that watches traffic and alerts staff but does not interrupt it. Which fits, and what changes if you need automatic blocking?
- Encryption choice: A laptop holding sensitive files might be lost. Which protection addresses data at rest, and why would transport-layer protection alone not help?
- Backup selection: A team needs fast restores with minimal storage. How do full, incremental and differential approaches trade off?
- Isolation: A guest network should not reach internal servers. What design achieves that separation?
Key Takeaway
When you practice, write down why each distractor is wrong. Objective-mapped practice with answer rationales builds the elimination skill that scenario questions reward. Our ITS-NS practice test is built around that approach, and you can keep the essentials handy with the ITS-NS cheat sheet.
Sequencing Your Prep Around the Hard Parts
You do not need an elaborate schedule, but ordering your study by difficulty helps. Start with the hands-on domain, because lab skills make everything else click, and finish with the conceptual layering that ties it together.
Operating System Security
- Set up a Windows and a Linux virtual machine
- Practice permissions, authentication settings and audit logs on both
- Enable and test disk or file encryption
Network Device Security
- Compare firewall, IDS, IPS and SIEM roles side by side
- Configure a simple firewall rule set and observe rule-order effects
- Review wireless protection and secure protocol choices
Defense in Depth and Secure Computing
- Map controls to layers and practice network isolation scenarios
- Work through backup selection and safe end-user computing cases
- Take objective-mapped practice sets and review every rationale
If you are weighing training formats, our overview of ITS-NS training options compares what to look for. Pearson's official preparation option, CertPREP powered by GMetrix, offers training and testing modes, but remember that practice-bank sizes and timers are not live-exam specifications.
The Real Cost of a Failed Attempt
Part of what makes an exam feel hard is the price of a miss. The US individual retail voucher that includes a retake is USD 133. If you fail, the issued retake code must be used within 60 days, so a failed attempt creates a clock you should plan around. The original voucher expires one year after purchase. Fees can vary by channel, and proctoring at a Certiport Authorized Testing Center may cost extra, so match your voucher to the delivery option you intend to use. The full breakdown is on our ITS-NS certification cost page, and scheduling details are covered in ITS-NS exam dates and scheduling.
Also note that awards earned on or after June 18, 2025 expire after five years, and renewal means buying a voucher and passing the current exam. Earlier awards remain non-expiring.
Don't Calibrate Against the Wrong Exams
A common source of misjudged difficulty is comparing this exam to others. This credential covers only the Pearson Network Security exam. It is separate from the ITS Cybersecurity and ITS Networking exams, and it is not Microsoft MTA or CompTIA Security+. Forum posts about those exams describe different scope, different scoring and different depth, so importing their difficulty ratings will mislead you.
The scope is also narrower than a broad cybersecurity syllabus. Stick to the four official objective headings rather than studying every security topic you can find. If you are still orienting yourself, start with what ITS-NS is and review how the credential fits into a career path in our ROI analysis.
Finally, be careful with salary expectations when judging whether the effort is worth it. The BLS May 2025 US median for information security analysts is USD 129,180, but that figure describes the occupation as a whole, not a certification-specific salary, an entry-level offer, or a proven pay premium. Our ITS-NS salary guide and ITS-NS jobs overview put that context in perspective.
Frequently Asked Questions
It is introductory in scope, but it covers four distinct areas across Windows, Linux, network devices and end-user behavior. Difficulty depends mostly on whether you have hands-on experience. Comparing it directly to other vendors' exams is unreliable because scope and scoring differ.
The published range is 35-45 questions with a standard exam time of 50 minutes, excluding administrative appointment activities. The exact total can vary by exam form, so avoid relying on a fixed number.
You need a 700 on a 1-1000 scaled score. This is not a raw 70% requirement, so the number of questions you must answer correctly is not a simple percentage.
No candidate-wide pass rate is published. Percentages from vendors or schools usually reflect their own cohorts and should not be treated as exam-wide statistics. Your performance on objective-mapped practice questions is a more useful gauge.
Pearson's candidate profile suggests at least 150 hours of instruction or practical experience in network security. That is preparation guidance rather than an exam requirement. Prioritize hands-on lab work with permissions, firewalls and encryption, then confirm readiness with realistic practice questions.
